You seem to have missed this key passage in the linked article, which makes it pretty clear Ecuador is backing away. They could issue another "letter of safe passage," but won't and are saying he should face U.S. authorities. The whole passport thing seems to be a fig leaf:

"An official at the Ecuadoran Embassy in London... had also issued a letter of safe passage for Snowden. But Snowden apparently did not use it for his trip to Moscow. And it doesn’t appear that the Ecuadoran government would make a similar gesture again.

"On Sunday, Correa told the AP that an Ecuadoran official at that embassy had committed 'a serious error' by issuing the first letter without consulting officials back home. Correa said the consul would be punished, although he didn’t specify how.

"Correa’s tone seemed to have shifted after a conversation with Vice President Biden on Friday. Where Correa had earlier been defiant, he now voiced respect for U.S. legal procedures.

“'If he really could have broken North American laws, I am very respectful of other countries and their laws, and I believe that someone who breaks the law must assume his responsibilities,' Correa said, according to the AP."
